Do you mean a command something like this?
(defun check-coding-system-region (from to coding-system &optional max-num)
"Check if the text after point is encodable by the specified coding
system.
When called from a program, takes three arguments:
CODING-SYSTEM, FROM, and TO. START and END are buffer positions.
Value is a list of positions of characters that are not encodable by
CODING-SYSTEM.
Optional 4th argument MAX-NUM, if non-nil, limits the length of
returned list. By default, there's no limit."
This could do the internals of the job. To be useful, it needs a user
interface.
How about if you modify it to make overlays to highlight those characters
instead of returning a list saying where they are?
